finally got the 205 running, but cant get the tacho to work

dont think i can use the input from the ECU

but have wired up the coil packs, like i did to get my elliot rev counter working and the tacho still dont work

starting to think there is an issue with the dash


anyone think of any ideas, any way to test the tacho?

would it require 12v or neg?

 

should req a -ve as a signal, im pretty sure.

 

Sorted now, just needed a signal from one of the coil packs now all four
